As far as I know, the whale hasn't problems with living in the sea despite being so similar to land mammals...

So why would a creator make it like a mammal and not a fish, it seems to me fish are far more adapted to the sea. They don't have to go up for air all the time. So why would you start off with a fish and say "No that design is too perfect, let's go back and make it worse and give it a load of organs it doesn't need while we're at it." |
I understand your point but still the whale hasn't problems.

It does have problems, the whale is really just a transitional creature. If it was 'created' to live in the sea why would the creator give it lungs when gills would do the job just as well? The lungs are just a constant problem, it has to keep resurfacing, fish don't have to surface.
The cetacean branch of evolution (Dolphins, Whales, porpoises, etc...) all have the same attributes that support that cetacean creatures once lived on land. Genetically they bare far more resemblance to land mammals than they do fish. the Cetacean creatures all fall under the Cetartiodactyla order, which is a a group of animals that includes not just whales, dolphins and porpoises but also land mammals such as hippopotamuses. We've even found staged cetacean fossils in Pakistan that show the transition from land mammals to sea mammals.
Just out of interest the attributes that these animals share are defined as...
1. Their need to breathe air from the surface;
2. The bones of their fins, which resemble the jointed hands of land mammals; and
3. The vertical movement of their spines, characteristic more of a running mammal than of the horizontal movement of fish.
